Processing custom Carbon Fiber Telescopic Pole expansion combination of straight pipe.

Product synopsis

Carbon fiber sleeve (CB) By the high quality carbon fiber yarn woven,Carbon fiber is a kind of excellent

mechanical properties of new materialsThe proportion of material, it is less than steel A quarter, the tensile strength of carbon fiber resin composite materials are generally in 3500 mpa In order to On the

steel is on the 7 ~ 9 Times, it has strong flexibility, resistance to high temperature, the proportion of light,

etc.The casing can be Used to set some irregular surface of wire, cable or hose, and good stability, high

torsional strength.

Carbon fiber is widely used in the car, aerospace, military industry and other high-tech fields.

Specification

Chemical properties

Due to the raw material, the modulus, strength and the degree of different heat treatment temperature,

the characteristics of different carbon fiber, the former hard and brittle is often used in composite material,

soft and supple commonly used in the textile;The latter is used for engineering materials.Because of more

and more than the application of carbon fiber properties, the urgency of the tensile properties of carbon fiber strength test before us.Finished strong stretching performance belongs to destructive test, the

sample without recoverability, after again for carbon fiber separation become single fiber is very fragile,

therefore in the process of each test, need careful, patient and do not cause damage to sample before

test.General test need to be technical index is the average of the CV value, etc.The tensile properties

of the carbon fiber monofilament and multifilament method test points.Carbon fiber separation become

single fiber is very fragile, low shear strength, fracture will be affected by any carelessness, therefore in

the process of each test, need careful, patient and do not cause damage to the sample.Single fiber

strength and performance test by using paper box fixed sample, usually, of course, does not rule out

other methods.Single fiber strength and performance test can test must be used with high strength and

high modulus fibers of carbon fiber, powerful instrument.Paper box method of fixed sample, shearing test

samples and the appropriate length of the carbon fiber with steel needle along the fiber direction its

separation, make the test samples fluffy facilitate extraction.To serve them with sample plate sample, in

order to guarantee the accuracy of the measured results, can't cause any damage to carbon fiber.Made

backing paper very troublesome foreign standards, in the process of test I use the computer mapping to

find a simple and feasible method.Take about 0.1 mm thick paper to do substrate;Profiling Word

according to the size of figure 1, create a suitable size box, copy the full A4 paper to print (figure 1 is 25

mm separation stretch size. If a 50 mm separation stretching, cutting tangent length should be doubled);

Ruler and tangent anastomosis after cutting blades for the solid part along the tangential cutting will be

cut, and then the two end with double-sided tape 5 mm wide;Extraction separation of single carbon fiber

test samples and placed along the center dotted line, and double sided tape fixed.Can also use melted

rosin, single carbon fiber "welding" on the paper box, the "spot" have the effect of fixed single carbon

fiber (trials show that: the "welding" way no double-sided tape and fixed way to use, and gripped sample

to leave "spot");With paper article 8 ~ 10 mm wide, covering double-sided tape in the direction of the

tangential cutting width and the end of the test sample, shear along the shear line, separated into fixed

sample under test in a single paper box.Note: carbon fiber sampling is difficult, especially after treatment

of carbon fiber, very thin, is also difficult to distinguish a root or two, according to the experiment curve

contrast to judge if the record the curve slope is significantly greater than the other sample is likely to be

two fiber, can take samples with a magnifying glass to cooperate when necessary.
